Keyboard Access (all models): the yx key.

Power analytic function.

Note: The HP49/50 uses a fast binary-tree algorithm to raise square matrices to integer powers.
Example:
What is the 128th Fibonacci Number?
    251728825683549488150424261 in 0.37 seconds on an HP50g.

HP49/50 maximum integer inputs:
y: no limit.
x: +/-9999 if y is also an integer.
